The GDI TAU engine in the 2014 Hyundai Equus is known for higher-than-average oil consumption, which can lead to frequent oil top-ups and potential engine damage if not monitored.

Direct injection engines like the GDI TAU are prone to carbon deposits on intake valves, which can cause rough idling, reduced performance, and increased emissions.

Some owners have reported issues with the timing chain tensioner, which can lead to a noisy engine and potential engine damage if the chain skips or breaks.

Fuel injectors in GDI engines can become clogged or fail, leading to poor engine performance, misfires, and reduced fuel efficiency.

The 2014 Hyundai Equus may experience leaks in the cooling system, which can cause the engine to overheat and lead to serious engine damage if not addressed promptly.

Various sensors, such as the oxygen sensor and mass airflow sensor, can fail, leading to poor engine performance and reduced fuel efficiency.

Due to the high performance of the GDI TAU engine, spark plugs may wear out more quickly, necessitating more frequent replacements to maintain optimal engine performance.

The 2011 Hyundai Equus with the DOHC TAU engine is known to have issues with oil leaks, often from the valve cover gaskets or oil pan gasket.

Some owners have reported problems with the timing chain tensioners, which can lead to a rattling noise and potential engine damage if not addressed.

There have been instances of coolant leaks and issues with the radiator and water pump, which can cause the engine to overheat.

Faulty fuel injectors can lead to poor engine performance, misfires, and reduced fuel efficiency.

Problems with various engine sensors, such as the camshaft position sensor or oxygen sensors, can cause the engine to run poorly or trigger the check engine light.

Direct injection engines like the DOHC TAU can suffer from carbon buildup on the intake valves, leading to rough idling, poor acceleration, and decreased fuel economy.

Premature wear of spark plugs can cause misfires, rough idling, and decreased performance. Regular maintenance is crucial to prevent these issues.

Due to the high performance of the GDI TAU engine, spark plugs may wear out more quickly, necessitating more frequent replacements to maintain optimal engine performance.

V-shaped engines, like the one in the 2016 Hyundai Equus, may develop oil leaks at the valve cover gaskets, rear main seal, and oil pan gasket due to the configuration and age.

The Direct Injection (GDI) system in the DOHC GDI TAU engine can lead to carbon buildup on intake valves over time, causing rough idling, misfires, and reduced performance.

The DOHC (Double Overhead Camshaft) setup can experience timing chain stretch or failure, leading to potential engine misfires or severe engine damage if not properly maintained.

V8 engines can generate significant heat, and the cooling system components (like the water pump, radiator, and thermostat) may be prone to failure, leading to overheating issues.

With eight cylinders, the ignition coils in the Hyundai Equus may wear out or fail, causing misfires, poor fuel economy, and engine hesitation.

GDI engines can experience issues with fuel injectors becoming clogged or failing, leading to poor fuel delivery and engine performance issues.
